This is skeletal (striated voluntary) muscle, showing both:
- Longitudinal section in the lower part, with parallel muscle fibres and faint cross-striations
- Transverse/oblique section in the upper part, where fibres appear as polygonal profiles
MBBS 1st-year identifying features:
- Long, cylindrical, unbranched muscle fibres
- Cross-striations in longitudinal section
- Multiple nuclei located peripherally, though they are not clearly seen in this low-quality field
- Connective-tissue septa between groups of fibres, namely endomysium/perimysium
So, write: “Skeletal muscle, showing longitudinal and transverse sections.” Skeletal muscle is striated, unlike smooth muscle. Histology: A Text and Atlas with Correlated Cell and Molecular Biology, p. 314.

You are right, I misidentified it.
This is most likely the thyroid gland.
Identifying points for MBBS 1st year:
- Numerous round to oval thyroid follicles
- Follicles filled with pink homogeneous colloid
- Each follicle lined by simple cuboidal epithelium
- Connective tissue septa and blood vessels between follicles
Write: “Thyroid gland, showing colloid-filled follicles lined by simple cuboidal epithelium.”
The lower striated-looking area is probably an artefact or adjacent tissue, not the main structure.
